This bloke, yourself, Tom Stanton's gas thruster quad copter, Xyla's materials science and design aesthetics,.... Got most of a Space Program right there!
This is so sick. I came from your tiktok, very glad I did. I’m going to grad school for GNC in the fall and I work in GNC atm, so this is very interesting to watch. Excited to see what you do with this, you got a bright future ahead of you man
would love to hear more about the TVC and simulator development. I’m very interested in that part of rocketry. I’m a mechanical engineer by education, so haven’t had too much rocketry exposure and it’s always cool to learn about it
Impressive stuff! Keep up the good work. It's not many recent HS grads who've made their own PCB & all the other things you've done - along with TH-cam documentation. You're going places, kid! Keep on truckin'.
Even as someone with very limited interest in rocketry - this was a must watch, and I’m excited for more. Personally I’d love to see a dedicated overview of the controller circuitry and its development process at some stage, but the general story of this project is absolutely fascinating…
Absolutely brilliant test of patience and determination. I’m excited to see what you have lined up in the future! I would think it would be fascinating to move to a larger scale to get more realistic and reliable telemetry data due to the overall mass increase. In addition a larger scale will allow you to see you more heat data, which will help you increase thermal efficiency, leading to longer flights. I am very intrigued with this project and approach to racketeering.
I launched my first (Estes!) model rocket in 1975, went into I.T. years later, but never married the two. Seeing you take this to a whole 'other level blows my mind. Sincere thanks for sharing - I'm looking forward to future videos!
Nice job Kofi! Having talked to a variety of senior projects teams, it seems like designing an Avionics system, especially one with PID control, seems like an extremely challenging task!
It's blokes like you and Joe Barnard who should be working on the Mars Sample Return project. You've accomplished so much here, at an enthusiast budget level, building skills and knowledge that will be invaluable to future human endeavors. Well Done!
Holy shot man, this is awesome! I have been working on and off on my own TVC rocket system for the last couple months (with varying progress) but after watching this video and seeing all effort and dedication you put into it I have reinvigorated to finish my own. You just earned yourself a new subscriber!
Kofi this is absolutely incredible!!! This is genuinely one of the coolest things I've seen someone do, and I'm so proud to be able to say I've worked with you :)
Congratulations for being persistent! :) I've had the idea to create such a system for my Engineering undergraduate project but it was much more complicated after a couple of researches :) Congratulations once again for making such a great job there!!!
Congrats on the persistence and resulting success! It's inspiring to see you kept at it over that time frame and eventually made it work - looking forward to your other projects :)
Great work! I'd like to see more on software, especially what measurements you're getting from the MPU6050 and how you're integrating them into the control loop. Thanks!
Coming back to watch it again for some inspiration and the STM32F405 jumped out at me this time. How did you get it to work with Arduino. I tried for AGES and finally abandoned my efforts.
Congrats on your work getting here! re: the flight computer software, huge kudos on your approach change (should I say "course correction"? :D ) between loop, RTOS, and then loop again. As a fellow engineer and now working with software, I know it takes a sizeable amount of focus and dedication to not fall for the sunken cost fallacy of "I've already implemented , I shouldn't just go back!", and recognize priorities in the wide sense!
Great job on the project! I would encourage you to record the overdub in a conversational tone, it can help a ton in conveying your excitement for your project. Keep up the great work!
That's super cool man! I love seeing the improvements you made from one version to the next. As far as the oscillation go on your last flight, it seemed like early in the flight the PIDs were too high but later on they seemed close to correct. Would doing some kind of speed dependent PID ramp be a good idea?
As am currently pursuing Bachelor's in Electronics and Communication Engineering, and I also designed my Flight Computer out of Raspberry Pi Pico RP2040 MCU and other sensors.. And since no idea about rocket motors, my Flight Computer just spending it's time laying around, and sometimes just records random data while sitting on RC quad coptor. 😢.. hopefully I'll make it work in an actual model rocket this year.
Very well done! Congrats! Also +respect for STM32 ;) I noticed Mahony filter mentioned in the code. So you do some sensor fusion? What data is involved besides the gyro? Would also recommend you to learn DMA and interrupts if you haven't yet. STM32 has amazing peripherals and you can offload so many things on them instead of wasting core cycles. That makes a HUGE difference in performance. As I can see from your code you are doing things like sensor reading in a blocking way (not 100% sure, sorry if you are not, not much code on the screen you know ;) ). That's not only a waste of CPU cycles but you may also have inconsistent time intervals for each "task". Instead, you can use hardware timers to schedule your "tasks" with precise time intervals and do sensor reads in a non-blocking way with DMA + interrupts. With that, you will get even better performance compared to RTOS. Good luck!
Thanks for your comment! I'm a big fan of your work! I used the Mahony filter to fuse gyro and accel data for orientation during ~1g flight and ground phases. I will definitely be exploring DMA and interrupts in the next project! I'm currently just using Arduino millis to schedule "tasks," but I would like to try out the hardware timers like you suggested. :)
I'd like to offer some ideas: 1. Would a Raspberry Pico be cheaper to use? 2. Have you considered using sugar (candy) rocket fuel. Just as much thrust as black powder, you could control the burn length, and, most importantly, it gives a slower lift off than than the black powder based Estes engines. This would give the servo controls more time to correct the flight. Also, cheaper once you have the engine casing.
This is such a great project! I was also attempting to build my model rocket with a software that displays Real-Time Telemetry, I was wondering if you have any recommendations or references as to that? I want to implement the motion tracking as well as the data, nice video btw :)
Thanks for watching, my next video will be about the flight computer and flight software! In the meantime, I recommend checking out BPS Space and Lafayette Systems if you haven’t already. They have lots of great information regarding real time telemetry!
I respect your creation my friend , even i tryied my first tailor made quadcoter fight controller in 2022 when i was in 9th class , but till now i did not learn it properly. Now i am studying in 11th standard now i have my peak tendency to learn physics and the mathematics behind multi rotor aircraft and more... but i am not getting support and the education of that.
@KofiAsare0 The good ol' 6050 IMU, nice! Did you pull individual x-y-z axis samples, or use fully-fused result? It would be neat to see you switch to a valved propellant system, to enable Falcon 9-like landings. That a high school graduate is developing his own TVC rockets... the future is looking very bright. Subscribed w/all notifs.
This is awesome!! It was great meeting you at FAR - can't wait to see more. Also nice job on the video too :)

It is fantastic to see BPS inspire others that will in turn inspire others. Nicely done!
This is awesome - really well done!
Awesome flights! I'm a huge fan of your flight computer layout too :)
What a time to be alive. One could access this information only by torture in 80's

Have you considered modeling this in simulink? you can simulate the control system and tweak it there, as well as auto code it into C
Will definitely be looking into it!
@@KofiAsare0hell yeah man! it comes included in the student version of MATLAB, im sure your college has a license
wow! I have been working towards TVC on my own flight computer, and I am just blown away by this work!

Yes CP and CG relationship is a crucial aspect in rocket flight stability.Great content.
Nice job Kofi! Having talked to a variety of senior projects teams, it seems like designing an Avionics system, especially one with PID control, seems like an extremely challenging task!
Such a cool video.
Great work with all the PID gains - I realise that it's not an easy task.
I subscribed to see the follow up videos you make.

TH-cam recommended this video. I'm really glad that it did. Great work!
Thanks for watching!
The last lunch test was amazing it had very great stability good job!
Nice work, I clapped on each successful launch! Love seeing the improvements over time. Look forward to another project you share! Never stop building
Huge props, what an achievement all by yourself!
Congratulations for being persistent! :) I've had the idea to create such a system for my Engineering undergraduate project but it was much more complicated after a couple of researches :) Congratulations once again for making such a great job there!!!
How did I discover this channel just now? TH-cam algorithm, you failed me.
Congrats on the persistence and resulting success! It's inspiring to see you kept at it over that time frame and eventually made it work - looking forward to your other projects :)
Good job. This is a cool project.
Very cool. 👍👍Don't forget the freezing of the integration when the actuators are saturated (max throws).
Great job! Awesome footage too
Great work! I'd like to see more on software, especially what measurements you're getting from the MPU6050 and how you're integrating them into the control loop. Thanks!

Duuuuude, great video and awesome explanations, thanks for sharing!
Great job Kofi. I saw the thumbnail and the Channel name and was like holy sh*t, i must see this. 😂😂😂😂. Just subscribed. Hoping to see more from you.
Great job bro! Cheers from Brazil!
Please do a detailed video of how you built and programmed the flight computer, Great video!!!
Very cool, congrats!
This was really cool, but I had to playback at .75. First time I slowed down a video.
Super looking forward the details on the FC design.
Awesome video! I would love to see more about the coding process and how the electronics work together
Amazing. Can’t wait to see what you do next.
Love your design, keep going!
Dude instant sub! This is so impressive
That is AWESOME Dude!
Impressive work and excellent presentation!
This is incredible! So many different disciplines executed... how did you learn how to all of these skillsets so quickly?
Great work, really awesome efforts and results!
Awesome job. We need more!
you are doing good bro! im encouraged 🤓

Really interested on how you design the flight controller from scratch. If time permits, please do a series on that one.
Ad astra!
Really impressive!
im hyped for this
Nice work !
Dude! Thats amazing fr
I’m interested in how you forked your sim software. Would love to see that video.
Gratz! i hope you can improve to next project with you gained experience.
Well done
Respect man !!
Can you explain how you made the PCB and programmed it in a future video? As well as how the simulations worked? I would love to see it!
